Jamison Basement Waterproofing Project Manager Steven Custus went out to meet with the new homeowners. Steve recommended a full perimeter drainage system. The GrateDrain (Closed) drainage system will drain the water from below the basement floor to the GrateSump. The GrateSump with an 1/2hp pump can remove up to 3,400 gallons of water per hour from the basement. We installed 3 GrateSumps because of the high volume of water this home was taking on.

This is a problem that we see all the time at Jamison Basement Waterproofing.

To address this, Project Manager Steve Custus recommended our 4 ft GrateDrain doorway entry drain, which channels water to the homeowner’s existing sump basin. We also upgraded the homeowner’s sump pump to a half-horsepower pump that can remove 3900 gallons of water per hour from the basement.

Now, for the first time in years, the homeowner does not have to worry when it rains.

The challenge we faced was that it was a tight area to dig, so we had to hand dig everything.

To address this, our Project Manager Ed went out and knew exactly what it would take to get the issue resolved quickly. He proposed an egress escape window and well. The township approved everything, and both the new homeowners and previous clients are happy.

The challenge we faced was that it was a pretty tough pump dig, but besides that, everything went smoothly.

To address this, we installed a Grate Sump with an airtight lid, a 1/3 horsepower Fast Sump, and a built-in pump stand to capture groundwater seepage, with the discharge line running to the back of the yard.

Project Manager Steve C went out and gave the homeowners a few options to keep the basement dry all the time , he even recommended starting with the Grate-Sump , sump pump and the wet area of the basement . The homeowners have the option of adding the perimeter drainage system at a later date . After few rains and the homeowners hearing the new Sump pump keeping the ground water below the slap during storms their problem is solved .

The challenge we faced was that the wall that was leaking was built on a slab. To address this, we built a wall one block high and then installed below-grade waterproofing on the outside.

Project manager Steve went out to meet with Vinny , after seeing the Hugh puddle in the middle of the crawlspace plus and few wall cracks that were currently leaking we knew this crawlspace needed a full encapsulation system with drainage system and a Grate Sump . Vinny had useable space in the crawlspace that he wasn't currently using after installing our system he now has almost 500sq of useable space that he plan on using for storage. Problem solved !
